What would be the main reason my heater controls don't work properly?
I have a 1995 Ford Mustang. When I put the switch on Defrost, Mix, or Floor, it always blows onto the windshield (Defrost). The air is hot, but no matter where I put the switch, it always blows onto the windshield. Is the problem in the switch, the heater control valve or should I look elsewhere? The blower motor itself works just fine.
